Instead of the famous large bear trap and 4 metal gates you can use metal fences and place one wall 3 high on 3 sides but on on the back of the giga place a metal door on the top (instead of the 3rd wall up) and once the giga is in open the door to the inside of the trap and giga cant escape. (If you found it hard to understand then I cant help🤷‍♂️) I have tried it and it works well 👍👍
